Biology

This bee's nest architecture is described by Sakagami and Michener (1962): Nest architecture is Type IIIb: Lateral burrows are very short or absent such that cells are almost attached to the burrow walls at a right angle. The cells are not spatially concentrated in any part of the burrow, and are at the end of long galleries.

The nesting biology of Lasioglossum villosulum is reviewed by Plateaux-Quénu (2008). Females produced at the end of summer mate with males and then overwinter (the males die before winter). These females then initiate new nests the following spring. They produce one generation of offspring that emerges early in the summer. Females of this generation mate and initiate their own nests. Offspring of the summer nests emerge late in the summer, and become the overwintering females for the next year. Thus, although this species raises two generations of offspring, it is not social because the offspring disperse away from the nest.
